Workpiece Support Suction Layout for Adaptive Emission Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece supports struggle to adaptively manage machining-related emissions during thermal machining, as they lack the ability to variably adjust suction power and positioning according to specific machining conditions, leading to inefficient emission removal.
Innovation Solution
A workpiece support system with a suction device that includes a vacuum generator and adjustable suction lines, where the opening width and position of suction openings can be varied using replaceable and adjustable wall elements, allowing for tailored suction power and location adaptation based on machining tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed suction openings are used in the workpiece support, then the structure is simple, but the suction power cannot be adapted to different machining conditions
Solution Approach 1:
The suction line incorporates adjustable wall elements that can be moved between different positions to change the opening width of suction openings. This dynamic adjustment capability allows the suction power to be adapted to different machining conditions while maintaining a relatively simple overall structure.
Solution Approach 2:
The invention changes the physical parameter of the suction opening (opening width) by adjusting the position of wall elements. This parameter change enables the suction power to be varied according to machining requirements without fundamentally changing the suction line structure.
2Object-affected harmful factors
If multiple suction lines are activated simultaneously, then all emissions are captured, but energy consumption increases
Solution Approach 1:
The suction system allows dynamic selection and activation of individual suction lines or groups of suction lines based on the actual machining position and emission generation. This enables the vacuum generator to operate at optimal power levels, consuming energy only when and where needed for emission removal.
Solution Approach 2:
Different suction lines can be activated locally based on where machining operations are occurring. This localized activation ensures that emissions are effectively captured at the source while avoiding unnecessary energy consumption in areas where no machining is taking place.
3Productivity
If suction openings are positioned far from the workpiece, then the structure is simple, but suction efficiency decreases
Solution Approach 1:
The wall elements with suction openings can be positioned dynamically to place the suction openings at optimal distances from the workpiece during machining operations. This dynamic positioning ensures high suction efficiency without requiring complex fixed positioning mechanisms.

AI summary
A workpiece support includes a workpiece support element and a suction device. A workpiece is mounted on a workpiece side of the workpiece support element during machining. Towards a remote lower side, the workpiece support element is permeable to a waste air flow loaded with machining-related emissions. The suction device includes a vacuum generator and a suction line. The vacuum generator is configured to generate the waste air flow flowing from the workpiece side to the lower side, to suck off the waste air flow into the suction line in a flow direction and to subsequently discharge the waste air flow via the suction line. The suction line has a suction opening having a flow cross section which can be passed by the waste air flow in the flow direction. An opening width of the flow cross section and/or a position of the suction opening can be variably adjusted.
